This time is different. It's got something to do with G$$GLE's policy to charge the Gmail users who happen to use their E-Mails under the so-called "G$$GLE Workspace". I know this for sure because I use Gmail under "G$$GLE Workspace" and today I'm greeted with a message like this "Your 14 day trial period for G$$GLE Workspace has ended. If you want to use G$$GLE Workspace , start a (paid ;) subscription." All of this happened after I've been using it for more than 12 years!

I've just tried this app on my Mojave MacBook and it's amazing. So pleased with it. My biggest requirement was an app as simple as an RSS reader must be open source and that it's got a macOS binary.
